      "value": "Agent Dart is an agent library built for Internet Computer for Dart and Flutter apps. Prior to version 1.0.0-dev.29, certificate verification in `lib/agent/certificate.dart` does not occur properly. During the delegation verification in the `_checkDelegation` function, the canister_ranges aren't verified. The impact of not checking the canister_ranges is that a subnet can sign canister responses in behalf of another subnet. The certificate\u2019s timestamp, i.e /time path, is also not verified, meaning that the certificate effectively has no expiration time. Version 1.0.0-dev.29 implements appropriate certificate verification."

Antes de la versi\u00f3n 1.0.0-dev.29, la verificaci\u00f3n de certificados en `lib/agent/certificate.dart` no se realiza correctamente. Durante la verificaci\u00f3n de delegaci\u00f3n en la funci\u00f3n `_checkDelegation`, no se verifican los canister_ranges. El impacto de no verificar los canister_ranges es que una subred puede firmar respuestas de canister en nombre de otra subred. La marca de tiempo del certificado, es decir, la ruta /time, tampoco se verifica, lo que significa que el certificado efectivamente no tiene tiempo de vencimiento. La versi\u00f3n 1.0.0-dev.29 implementa la verificaci\u00f3n de certificados adecuada."
